- Abstract:
- Under the condition of no tillage with mulch which amount was above 4 500 kg/hm2,increase of corn yields was 22.15%~25.65%; the water utilized coefficient of soil can increase 2.962 5 kg/(mm·hm2); compared the treatments of no tillage with mulch to the traditional tillage,the contents of quick moving available water in 0~200 cm soil layers can increase 17.02~47.9 mm before spring sowing.There was a significant negative correlation between earth cumulative temperature in 5,10,15 cm soil layers and the amounts of stalk mulch;the more the mulch amounts were,the less the volume weight in 0~10 cm soil layers was; the significant relations of linear regression were formed between organic substance,total N,available P and mulch amounts.Compared the treatments of no tillage with mulch to the traditional tillage,amounts increased of urease,basic phosphatase,invertase were 0.04~0.48 mg/g,0.05~1.08 mg/g and 1.7~12.8 mg/g; there was a significant linear correlation between the three kinds of enzyme and the amounts of mulch.
